The Zero Trust security model is a response to the changing work landscape, where traditional perimeter-based security models are no longer effective due to the increasing use of cloud apps and remote work. It assumes that all users, devices, and applications are potentially compromised and requires constant validation of trust. This model has its roots in the 2010 Google Operation Aurora cyber attack, which highlighted the limitations of perimeter-focused security. To implement Zero Trust, companies must adopt a multi-factor authentication approach, such as passwordless logins using passkeys and WebAuthN, and integrate tools like WorkOS for session management, SCIM, and fine-grained authorization. The goal is to make users act paranoid and constantly verify everything, assuming that attackers are already inside the network.
